title: Antigen Nou. A new high frequency Rh antigen.
abstract: Serum from a D--/D-- allo-immunized woman is found to contain 3 separable antibodies: anti-e, anti-Ee (Rh 17) and a third component which, in contrast to 5 other sera from people with Rh deleted phenotypes, reacts strongly with red blood cells from Mrs Nou., a DIV(C)--/DIV(C)--black woman. The latter component studied by elution and coagglutination using Nou. cells reacts with a hitherto unrecognized public antigen within the Rh system. 2750 random donors, 2Rh mod. individuals and 17 people with public minus phenotypes in other blood group systems were found to express the antigen. 2 Dc--/Dc--, 4 D--/D-- and 4 Rh nul samples were non reactive. The identity of the antibody with anti-Hr (Rh 18) was ruled out since the original anti-Hr failed to react with Nou. red blood cells.
